I know that now it is closed and you can't receive sP for sending the score, but would you be able to receive the achievement for it?

I don't think so, since you'd have to send the score before it knows you got it.

why is the game closed ?

Dang! I was waiting for the HS's to reset cry

i just send the score for the game....and yesterday or 2 days ago as well........

I sent a score yesterday and although it said it sent, I didn't recieve it.

i just checked right after i read this thread and before posting, to make sure.... playing once is not a killer....

I believe it has been fixed since the OP was made. :) At least the message at the top was taken down.
